IMPROVEMENT lN CARS FOR ONE-RAIL RAlLRCADS.

Specification forming part of Letters Patent No. 170,692, dated December 7, 1875; application filed November 12,1875.

To all whom 'it may concern:

Be it known that I, ROY STONE, of Vandalia, Gattaraugus county, New York, have invented an Improvement in Locomotives and Cars for One-Rail Railroads, of which the following is a specification:

My invention relates to an improvement in locomotives and cars adapted to one-rail railroads-as, for instance, the car for which Letters Patent were granted to me on the 20th day of April, 1875, numbered 162,823-the main object of my invention being to prevent the imparting of shocks to the car, and to insure comfort to the passengers.

In the accompanying drawing I have illustrated my invention as applied to the car with horizontal guide wheels, as described in the aforesaid patent; but it should be understood in the outset that the main feature of my invention is applicable to all such cars for traversinga single rail as have guide-wheels for insuring lateral steadiness, whether such wheels are horizontal, vertical, or inclined.

Figure l of the drawing represents a vertical section of part of the said patented car with my improvements; Fig. 2, a section on the line 1 2; and Fig. 3, a detached sectional view of one of the guiding-pulleys.

The dotted lines in Fig. l represent an outline of the trapezoidal truss-frame or girder for which Letters Patent N o. 162,504 were granted to me on the 27th day of April, 1875, the main rail for the driving-wheels of the locomotive and forthe main supporting-wheel of the cars being secured to the top of the girder, each inclined side of which terminates below in a guide-rail, a, for the horizontal guiding-wheels B, the rim of which is clothed with rubber about an inch in thickness.

It has been proposed, in constructing cars for one-rail railroads, to make yielding bearings for the spindles ofthe guide-wheels. Such a provision, while it may tend in a slight degree to lessen such shocks as may occur when the car arrives at a curve of the track, or when the wheels pass an obstruction on the guiderails, cannot produce a satisfactory result, for under such circumstances the inertial of the wheel and that of its bearings must be overcome before any yielding takes place, and consequently there must be a shock of more or less severity, which tends to injure the car, and is a source of discomfort to the passengers. I entirely obviate this difficulty by clothing the rim of the pulley with rubber, which yields immediately to any irregularities or obstructions on the guide-rails, and to any lateral movement of the car when it traverses a curve of the track, and at once absorbs the shock which would otherwise be communicated to the car.

In the drawing, D represents part of the body of my said patented car; and E and E',

,two of the sills, to which I hang the guidepulley B in the following manner: Two plates, G and H, are secured to these sills, and a stationary spindle, I, passes through and is se--` heavy loads, or to obstructions on the mainrail.

I prefer, however, to make the distance between the ianges of the guide-wheels greater than the thickness of the guide-rails, so that slight vertical movements of the car will not raise or lower them.

It will be observed that the securing of the two plates G and H together by the stationary spindle I insures a substantial, and at the same time comparatively light, structure for carrying each guide-wheel, the plates themselves being, by preference, made of sheet or bar iron, and having such langes for attachment to the car as the construction of the latter may suggest.

I prefer to construct the guide-wheel in the manner shown in Fig. 3, on reference to which it will be observed that the wheel is made of two parts--namely, the flanged body m and loose flange u', the rubber ring g being forced onto the rim of the wheel before the loose flange is secured to the same.

I claim as my invention- 1. The combination, with a car adapted to one-rail railroads, of rubber-rimmed guide- Wheels, substantially as herein set forth.

2. The combination of the plates Gr and H, secured to the frame of the car, with a stationary spindle carrying the guide-Wheel, and serving to secure the two plates together, as specified.

3. The Within-described guide-wheel, con-v sisting of the anged body, removable flange, and intervening rubber ring g, as set forth.

In testimony whereof I have signed 'my name to this specification in the presence of two subscribing witnesses.

ROY STONE.
